Solutions for mining and mining industries
Mining and processing plants and enterprises of extractive industries are the largest consumers of electric energy. The peculiarities of the organization of transmission and use of electricity in these industries are the extreme operating conditions of equipment in mines, open-cut mines and deposits. The operation of equipment in open spaces, the dispersion of equipment over large areas, the regular movement of the work front, the inability to ensure constant voltage levels during operation of powerful electric drives – all this causes special requirements for the reliability and safety of the machines and electrical equipment used.
The specifics of mining and enrichment technology require the use of highly specialized equipment samples, such as explosion-proof electric motors for operation in an environment of explosive mine gases, as well as special types of pumping equipment (slurry, foam, ground, sump pumping units).
Energospetsmash supplies electric power and pumping equipment for mining and processing enterprises in a wide range of capacities and performance characteristics. The priority when choosing equipment for enterprises in the extractive industries is the reliability and durability of structures of electric machines, switching and distribution devices, pumping and compressor units. At the same time, the energy efficiency of the equipment is not ignored, which ultimately determines the cost of the life cycle of the technological installation and production as a whole.

Special electric motors for GOK by fields of application
Mining electric motors
The most stringent requirements for explosion protection of equipment are applied to machines operating in underground mines and workings where flammable mine gas or combustible dust is present. Special requirements are imposed on electric motors capable of operating in such conditions – the design of the machine must resist the spread of possible ignition of the combustible mixture, without destruction with the possible propagation of the shock wave of the explosion.
Energospetsmash supplies electric motors of all three explosion protection groups, including mine electric motors of the most responsible, group I, in a wide range of capacities and in various versions for mounting positions, with special requirements for shaft sizes, with additional conditions for equipping sensors, etc.
Electric motors for mills and crushers
Energospetsmash supplies electric motors that have proven themselves reliable as a drive for mills and crushers in mining and processing industries. The rigid and durable power circuit of the engine design most effectively perceives sharp alternating loads from the mechanisms of mills and crushers, increased values of starting and operating torques ensure uniform and smooth operation of mining equipment in the most adverse conditions. Modern structural and insulating materials, which are used in engines supplied by Energospetsmash, provide an increased service life of electric machines and an extended interval between scheduled technical inspections of equipment.
Electric motors for belt conveyors, pumping/fan loads, etc.
Energospetsmash supplies high-power electric motors for belt conveyors, large industrial pumps and fans. Modern designs of electric motors supplied by Energospetsmash for mining and mining enterprises guarantee a long service life at low operating costs.
Gearboxes and gear motors for mining and mining industries
Gearboxes and gear motors supplied by Energospetsmash are reliable and energy-efficient equipment with a long service life. We offer to supply gear units of the widest purpose for the production processes of mining and processing plants.
The advantage of the gearboxes and gear motors offered for delivery - the modularity of the design - provides ample opportunities for creating combined units for certain application conditions.

The task of regular diagnostics and updating of the instrument base of production lines is of particular importance, given the high requirements for the reliability of control and automation systems, electric power switching and regulating devices. Frequency-controlled drives (VFDs) are also of crucial importance, which determine the energy efficiency of production equipment. Along with soft-start devices, frequency converters allow you to smoothly turn on electric drives and load them evenly, saving the life of not only electric motors, but also mechanical transmission on a variety of technological lines and installations.
